Is this a sign of burning oil? The two ports are very black, and I just replaced the exhaust manifold today. The car is a 2017 inline-4 with 226,000 miles. It has restored 100% of its power now! It burns 1,000 mL (1 quart) of oil every 1,000 miles. Can I soak the old exhaust manifold in water? Will it help clean up the ash from the burning oil? So i can reuse the old one nezt time since is out
